BUMPER AND COUPLING FOR MINE-CARS. I

Patented Jan. 23,1913.

Application filed December 29, 1911. Serial No. 668552.

" vhas for its object the provision of a construction which will provide for maximum stability and at'the same time provide for a ready coupling with a car having a similar construction or one provided with a side 'b'um erstructure in which-the coupling link similanrefeience characters indicate similar is/located on a diflerent plane from the gen- 20;eral type of center bumper structures now in general use.

To these and other ends, the nature of which will be readily understood as the invention is hereinafter disclosed, my invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawingsand particularly pointed out in.the appended claims.

Ina-theaccompanying drawings, in which parts in each of the views, Figure is a vertical longitudinal section of a portion of a minecar with my' improved construction same.

in place; Fig. 2 is a top plan view of the cast-ing which forms the principal part of my invention. Fig. 4 is a sideelevation of the same; Fig. 5 is a perspective view of a modified form of the castin Fig. 6 is a detail perspective view sho ing another modified form.

Referring to the accompanying drawin s,

210 designates the-casting which forms t e principal element, of the present invention, serving as a bumper, a link support, and having a particular configuration which coacts with the framing of the car in such manner as to cause all of the parts to co-act to increase the stability of the construction.

The casting is formed with three hOIlZOIltally extending walls, 11, 12, and 13, located on spaced-apart planes, the lower wall 11 extending throughout the lateral length of the casting, the wall 12 having a lateral length less than the-length of the wall 11 Fig. 3- is a front elevation 'of the and being located approximately central of such length, while the wall 13 is formed in two parts, each being of a lateral length approximately equal to the distance between the side of the bumper and the vertical pl ane of the side of the wall 12, the three walls being preferably 'formed integral with the 4 front or bumper face 14 of the casting, the latter face being of proper configuration,

preferably slightly curved throughout a part or the whole of its direction of length. As

shown in Fig. 3, this provides a facial appearance of a'bump'er having a depressed central portion, the bottom of the depression being the top surface of the plate or wall12.-

As will be seen by reference to Figs; 2 I

and 5, the wall 12 has its sides extending-on lines converging from the front or bumper face, the distance between' the top plane of the wall 12 and the bottom plane of the walls 13 being provided by vertically extending webs 15, which, like the wall12, project rearwardly beyond the rear end ofthe walls 11 and 13, the wall 13 overlapping the top planes of the webs 15, thus providing a structure in which the walls 13 project above the top plane of the remainder of the casting. The webs 15 may be of any desired configuration 'at the rear of the wall 12. For instance they may extend simply in the plane of their direction of length, being unconnected at their rear ends excepting to the wall 12, as shown for instance in Fig. 2 in dotted lines; or if desired, the

ends of the web may be connected by a web 16 as is shown in Fig. 6, or this web may be increased in size to project forwardlya considerable distance to provide what .may

be termed a block 17 formed integral with the webs 15 as shown in Fig. 5 and which would serve the same function as the separate block shown in dotted lines at 18 in Fig. 2.

' The casting is placed in position with the upper surface of the floor planks 19 substantially on the plane of the lower surface of the walls 13, thewalls 13 resting upon said floor planks as indicated in Fig. 2, the planks being arranged to provide s. su port to the rear face of the webs 15 and 16 if the latter I be used) or the block 17, as shown in said Fig. 2, with the result that all strains or pressures; placed on the bumper in a d rection lengthwise of the car are also placed on the supporting timbers (planks 19), so

' 35 ment' of -45 ing strain thereon is that the' latter bumper structure. v l

- The planks 19 may be of any desired thickness, any space which may be left helow the bottom plane of the planks and the plane of the upper face of the wall 11 being filled by filling blocks or planks 20, an example of which is shown in Fig. 1, this construction providing for a ready assemblage w of parts and at the same time adding stabilityto the construction. I v

The bumper casting is secured to the planking 19 (and the filling blocks 20, if

the'latter be employed) by means of bolts 21 which extend through the casting from top to bottom, passing through the walls 11 and 13; they are further secured by means of a bolt 22, which extends through an 1 opening 23 formed in the wall 12 and in the block 17 M18 as the case may be, located afi ord 1 support for the;

' above the top plane of the wall 12 as shown in- Fig. 1, the bolt passing through the fill ing block, if employed, and through the belt 24 Which. has its direction of length ex- 25 tendinglaterally of the car, and the drawbar 25, the construction being such that the parts are firmly, secured in position by means, of said bolt 22. v As shown in Fig.1, the draw bar 25, the

Wall 12, the filling block'QO and the wall 11 areproV'ided with alined openings 26 for the passage of the pin-27 for the coupling, There are a number of positive ad vantages which result from this particular arrangeparts, among which may be stated the following: By reasonof the depressed portion providedby the wall 12, which wall 'acts as a support for a link 28, the drawbar 25 extends in a substantially single 4 plane, instead of being required to be bentat an angle as in constructions of the present day, thus not only placing the front of the draw bar within the planeof the bumper, but at the same time providing that the pullexerted entirely in the plane of its direction of length and insuring that the openings for the pin 27 will not readily pass out of alinement. This particu- 1n arrangement, in connection with the fact that the side walls of" the depressed portion converge toward the rear, by means of 'which construction the link is caused to be retained in a position where coupling "is readily effected, tends to entirely eliminate liability of the forward end of the draw-bar being bent upwardly, a result which. is com mon in constructions now in general use. An additional advantage lies in the fact that there is a positive support provided for so the blocks 17 or '18, as the case may be, by

the walls or webslfi; where the block is separate,' as-indicated at 1'8, the-wedge effect of the webs -on the corresponding walls of the block 18 would act as a support to take any strain which might be provided by movements of the lin'k s 28 into contact said block, of? of the'bolt 22; andwhe1'e'the block is formed integral', as at 17, the

the bolt '22 is not subjected to stralnssnan might weaken it, especially as this per tlon of'the casting .18 supported bythe planks 19. Furthermore, the particular configuration of bumper in connection with of the link supportnt a point below the normal plane iof the bumper, places the link in position where it-can readily enter the coupling head of amine the locating car equipped with the side or double bumper structures, without requiring the link to vary materially from an approximate horizontal plane; this is of especial importance since any material variation would tend to throw the car off of thetrajck, ahd'by reason of the extended lateral length of the bumper f casting, the device will co-act with the bumpers of the cars equipped with the'jside or double bumper; a j 3 1 As will be readily'understood, the particular construction shownis such as to provide for a maximum stability,a simple-and eiiicient operation, a durability in construction, and a construction t-hat'can-be made and placed in position at a'relatively-low cost, and which can .beinstalled'in'; cars in substitution of bumper structures thereon without materially affecting-the construction of a car itself. .0

While I haveherein shown one or more forms in which my invention may hecarried out, it is obvious that variations and changes therein may be required or desired in use, .and I desire .tobe understood as -reserving the right to make any and all such" changes and modifications in the structure and combmation as may be requlred orde':

sired, so long as such changes and modifica--.

tions fall within the spirit and scope of the invention as expressedin the accompanying claims.

I claim as new is:-- p

l..
